Times inserted like this will not interact with the clocking
feature - probably just what you want in this case.

Why would you want to turn off the clock?  It is actually
not running, only a starting time is recorded.  Just "start"
it again when you need a new clock.

I agree, for this application you don't want this.  Just a hot key to  
insert the time,
or even a full headline or plain list item with the time included.

Of course this is possible, but code for that would need to be written.
